String manipulation in javascript object

I am trying to populate the following string if I have n data:

group.items[0].fname || group.items[1].fname ||..........|| group.items[n].fname

I have implemented following, I would like to know is there a better way to do that?

nam="";
for (i = 0; i < data.length; i++) { 
  if(i==0)
    nam="groups.items["+i+"]"+".fname";
  else
    nam=nam+"||"+"group.items["+i+"]"+".fname";
 }

Since data is an array you can simply use Array.prototype.map to build array of substrings and then join them:

var data = [1,2,3];

var nam = data.map(function(el, i) {
    return 'group.items[' + i + '].fname';
}).join('||');

alert(nam);
